Texas Instruments UCC25660 | Demoboard UCC25660EVM-064

Description

The UCC25660EVM-064 assists designers to evaluate the operation and performance of the UCC25660x LLC Resonant controller (16-pin SOIC package with removed pins for high voltage clearance). This evaluation module demonstrates how UCC25660x controls the LLC resonant half bridge DC-DC converter to achieve high efficiency through out the load and input voltage range

Features

IPPC controlled (Input power proportionalcontrol) LLC resonant half-bridge DC-DC powerconversion

• DC line input from 365 VDC to 410 VDC
• AC input voltage from 85 VDC to 265 VAC
• Regulated 12-VDC typical output
• Full-load power of 180 W, or full-load current of 15A
• High efficiency
• Enhanced light load management:– High frequency pulse skip for improved lightload efficiency– Low frequency burst for reduced standby power– Audible frequency range skip for reducedaudible noise– User option to disable– Integrated PFC on/off control signal
• Combined resonant current and resonant capacitorvoltage sensing through one pin
• Adaptive dead-time
• X-capacitor discharge
• Automatic capacitive region avoidance
• Adaptive soft start with minimized inrush current
• Complete sets of protections:– Cycle-by-cycle current limit, OCP1 protection– Configurable over power protection– OVP, internal & external OTP– Vin & VCC UVLO– Inbuilt 19.5 V VCC Clamp
• Test points to facilitate device and topologyevaluation
